Overview
The BYV29-300-E3/45 is a single fast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage of 300 V and an average forward rectified current of 8.0 A. The device exhibits a maximum reverse leakage current of 10 µA at rated voltage and a typical forward voltage drop of 1.4 V. Key electrical characteristics include a maximum non-repetitive peak surge current of 125 A and a maximum reverse recovery time of 50 ns. It operates within a junction temperature range of -55 °C to +150 °C and is housed in a TO-220AC package.
Feature Summary
- Fast recovery switching capability with a maximum reverse recovery time of 50 ns
- Glass passivated junction for enhanced environmental stability and reliability
- High thermal performance supporting operation up to a junction temperature of 150 °C
Applications
- High-frequency AC-to-DC conversion circuits
- Free-wheeling diode applications in power supplies
- Inverter and chopper circuits requiring rapid switching
Procurement Notes
Verify the specific suffix designation against the manufacturer's official documentation, as variations may exist. Confirm RoHS compliance status through the latest datasheet revision. Ensure the TO-220AC package dimensions match your PCB footprint requirements. Check for any REACH SVHC declarations relevant to your region. Validate that the component meets the required thermal dissipation specifications for your enclosure design.
Selection Notes
Select this component when a single-phase rectifier with 300 V blocking capability and 8 A continuous current rating is required. The 50 ns reverse recovery time makes it suitable for higher frequency applications compared to standard rectifiers. Consider the TO-220AC package for through-hole mounting and adequate heat sinking. Evaluate the 1.4 V forward voltage drop for efficiency calculations in low-voltage output stages.
Part Context
This part belongs to the BYV29 series of glass-passivated fast recovery rectifiers from Vishay. These devices are designed for general-purpose high-speed switching applications. The series offers various voltage ratings while maintaining consistent current handling capabilities. The E3 suffix indicates lead-free termination compliant with international standards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's cross-reference guide or authorized distributor databases for equivalent components with matching electrical parameters and package styles.
